Hello,
We have several mailboxes in our Exchange Online environment that we want to use in our Dynamics 365 environment to send out emails. Right now it seems like the only way is to give the mailbox a Dynamics 365 license to get it to show up as a user and after that we can configure the mailbox in Dynamics with server-side sync and use it for workflows etc that automatically sends out emails etc.
The problem here is the cost of a license. Therefore, I have been looking into non-interactive users, but you can only have maximum 7 of those in one environment. We have double the mailboxes that we want to use for this.
Does a service user like this actually need a license? This is not a user that is going to be used to login and do stuff, only for outgoing emails.
